Abstract: Bistable high-performance miniature relay, comprising an insulating housing having a first housing chamber (1b) with a single-phase contact assembly (4) with two current bars (8a, 8b) and a contact spring (13). The contact spring (13) being permanently connected with one leg end a current bar (8a). In a second housing chamber (1a), a bistable magnetic actuator assembly (3) with a pivotable armature (11) is placed. The contact assembly (4) and the actuator assembly (3) are located in one or two planes in the insulation material housing, the contact assembly (4) is provided with a multiplate contact spring (13) bent U-shaped to a current loop, and the actuator assembly (3) is provided with a one-part U-shaped yoke (14) with an excitation coil (17) per yoke leg and a yoke central leg (16), borne by a flat permanent magnet, supporting a rocker armature (11) formed in a slightly V-shaped.

Abstract: A magnetic trigger mechanism with a yoke with armature opening. The armature is coaxially surrounded by a coil having an excitation coil, which is acted on by a force of a preloaded spring and which remains in a first end position due to magnetic holding force of a permanent magnet when there is no current flowing through the excitation coil. The permanent magnet is arranged at a first end of the armature and the second end position of the armature being achieved by a brief flow of current through the excitation coil together with the accompanying lowering of the magnetic holding force and the spring force. The first end of the armature is guided in the coil body, and the second end position, which faces the armature opening, is guided by a centering ring, the highly permeable centering ring rests against the yoke at the armature opening and can move.

Abstract: In a bistable magnetic actuator with a polarized magnetic circuit with parallel operating air gaps, wherein between the outer legs of a U-shaped soft-iron yoke a flat permanent magnet is integrated that carries a soft-iron center leg and applies a permanent-magnetically created magnetic flux to a rocking armature supported on the center leg, wherein at each outer leg a separately controllable excitation winding provides swiveling pulses for the rocking armature to swivel from one permanent-magnetically self-holding swivel position into the other, the permanent-magnetically created magnetic flux through the magnetic circuit closed over the rocking armature in each case for an electromagnetic magnetic flux created by the excitation winding of said magnetic circuit in a direction opposed to the permanent-magnetically created magnetic flux commutates into the other parallel magnetic circuit with the electromagnetically not excited excitation winding, swiveling over the rocking armature.

Abstract: A multi-stage planetary gear train, with several annular segments arranged between the adapter plates of the motor and of the gear head, each annular segment has a planetary gear set comprising a sun gear, several planet gears carried by a planet carrier, and a ring gear having inner teeth. Adjacent annular segments are coupled to each other and the outer segments are coupled to the respective adapter plates. The annular segments and the corresponding adapter plates in the region of the adjacent end faces thereof form a coupling area each, and the segments each comprise at least one engaging element on one end face thereof and at least one complementary receiving element on the opposite end face thereof, wherein the engaging element of a segment engages with the receiving element of an adjacent segment or of an adapter plate in a form-fit or force-closed manner in the assembled state.
